| 摘 要： | 提出了一种数据同步采样方法.该方法首先采样出线路两端的电流相量,并在此基础上应用延时修正方程和傅里叶反变换算法求得延时同步修正参数,然后根据延时同步修正参数进行线路两端电流相量相加.应用PSCAD软件建立配电网仿真模型对该方法进行了仿真验证.

| Abstract: | A new kind of synchronization method is proposed in this paper.Firstly this method sample out the current phasors of the both ends of the line,and delay correction equation and Fourier inverse transform algorithm are applied to obtain delay synchronous fixed parameters.The current phasors on both ends of the line are combined according to delay synchronous fixed parameters. |
